To make sure that his defenses would be at an appropriate level, Luke wounded himself in his dimension with swords that were enchanted with fire and ice magic. He didn't forget the image that he saw on that planet, so even though it was mentally exhausting, Luke leveled up his fire and cold Resistance up to a rare rank. It was annoying that his clone couldn't be the one suffering the damage, but in the middle of that session, Luke made his clone wound him with Fireballs and Ice Arrows. Thus, he learned and obtained all the points until the skills reached the rare rank as well.
"This should be enough for defense, but now for the way, I should attack them… Should I go doing the usual physical attacks?" Luke rubbed his chin thoughtfully.
